Add Push Button to View Pin Map

This example shows how to use matlab.system.display.Action to
add a button to the block mask. When you click the button, an image
of the hardware board pin map opens. The example shows how to set
button options and use an actionData object input
to store a figure handle. That way, the same figure is used when the
button is clicked multiple times, rather than opening a new figure
for each button click.
